Trinary switch wiring help

[Alex200mph]

Could someone do me a favour and tell me the colours of the wires going into the block connector and the colour of the corrisponding wire going out please..

Its on the passengers inner wing under the bonnet. Its mounted on the ali air con lines and there should be 4 wires I think. Will try and post a pic. Its a T350 btw.

Many thanks for the help.

Thanks Al. Yes it's the clear block connector on the left. The wires in and out.

I replaced mine a month ago.
On my sag the remaining clear juction block thats left when i removed the faulty trinary switch did not connect direct on to the new switch clear connector that comes on the new trinary safety lp switch. [guessing this is your problem]
So you need to cut off the new and old connectors , join the wires by colour[dont think the 4 black wires matter] and then heat shrink. [stops water damaging]

The wires from the loom side going into the block connector came out. I have a black wire, green/pink, white, and white. On the Tinary side I have green/black, green black, blue, and blue. I have wired up how I think it went but not completly sure I have got it right.

Also getting a ambient air temperature sensor fault even though I have replaced with a new one. Not sure if this is related.

Thanks for any help!

Not sure if this will help, I have a Griffith 500 with 4 pin trinary switch connector with the following wiring.

Loom side - white, green/pink, white/black, black.
Trinary side - red/white, blue/white, black/white, blue/red.

Connected such

white - red/white
green/pink - blue/white
white/black - black/white
black - blue/red

when I was checking my wiring pretty sure green/pink was fan activation and black was negative, would therefore assume the other 2 wires were the hi or low pressure activation

Thanks Oz. Will have a look at the connections today and see if I can get it sorted!
